$2.$ For $()=+1$ a$)$ Find the slope of the tangent line at the point when $=4$ b$)$ Find an equation for the tangent line to $()$ at the point $(4,94)$ c$)$ Consider the answers you found for a$)$ and b$)$ above. Think about the difference between being asked to find the slope of the tangent line and the equation of the tangent line. The slope of the tangent line is a $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_,$ while the equation of the tangent line is$,$ of course, an equation.
